Frequency :1090MHz.High Gain :5.5dbi .Length :60cm.Antenna Connector :N female& 16.5ft SMA male RG58 Cable. Suit for radio dongles ADS-B DVB-T DVBT Defined Radios SDRs USB flightaware pro stick NooElec NESDR SMArt - Premium NooElec RTL-SDR stic Aluminum Enclosure and Flight Radar 24.Works with Raspberry Pi and Windows PC. Material ：(antirust) the antenna is made of fiberglass. The antenna structure inside is made of copper.The copper (element) tube is better than the circuit board. The copper (element) tube enables the antenna to obtain lower VSWR and withstand higher power. Buy this antenna to improve your ADS-B signal. You can see more planes at a greater distance. Use skills:Any antenna is heavily dependent on the surroundings.To achieve better results you may have to move around your hotspot and antenna（height and location of the installation）until you determine a sweet spot that gives you the best rewards.You must take into considerations, antenna hight, location,building clearance, line of sight,etc. Lightning arester:If you need to mount the antenna on a roof or very high, and you are in a lightning-prone area, it is recommended to install a lightning arrester.if you need you can buy it in my Amazon store. Dimensions of the mount :The mount fits poles whose diameter between 35mm and 50 mm.(as the picture ) Power:the 1090mhz antenna does not require power,it is just plug and play ,don't need any setting up. if need the lighting arrest and the LMR400 cable or other antenna,you can enter my store and order.
